Which Elden Ring boss is titled Malenia, Blade of Miquella?

The Elden Ring boss titled Malenia, Blade of Miquella, is Malenia.

Malenia is one of the game’s major optional bosses and a demigod daughter of Queen Marika the Eternal and Radagon. She is the twin of Miquella, whose name appears in her title and in the lore surrounding the Haligtree.

Her battle takes place at the base of the Haligtree in an area reached through a difficult optional quest and exploration route. Malenia is famous for her prosthetic arm, exceptionally aggressive swordplay, and the Scarlet Aeonia associated with her second phase.

The title is sometimes shortened to “Malenia” in ordinary conversation, but her full boss name is “Malenia, Blade of Miquella.” She is not the same character as her mother Marika or her twin Miquella.
